1.27mm Box Header Double Row SMT

This is a 1.27mm Pitch Double Row SMT Box Header (male connector with protective frame), using SMT (Surface Mount Technology) mounting, primarily for high-density interconnection between two PCBs or board-to-board traces.

• It enables high-density electrical interconnection and supports signal transmission.
• The box design provides mechanical protection, alignment guidance, and prevention of mis-insertion.
• The SMT design is suitable for automated placement production, significantly improving assembly efficiency.
• It helps reduce the size of finished products, simplifying the assembly, maintenance, and upgrade processes for electronic products.
• It provides a stable connection, easily replaces old connectors, and saves time and labor cost

• Housing: High-temperature thermoplastic, UL94V-0 flame retardant rating. Provides good heat resistance and dimensional stability.
• Contacts: Copper alloy, offering excellent elasticity, high conductivity, and fatigue resistance.
• Plating: Contact areas use Flash Gold (standard 0.8μm), with options for thicker gold plating or tin plating. Gold plating provides excellent oxidation resistance and low contact resistance.
• Structural Features:
• Double Row configuration.
• SMT terminal, suitable for reflow soldering.
• Featuring a box header design, it enhances mechanical strength and alignment accuracy.
• The overall structure is compact and low-profile, making it suitable for thin PCB layouts.

Main Electrical and Mechanical Specifications

Suitable for modern electronic products requiring space constraints and high-density interconnection, primarily including:

• Power Systems.
• Communication Networks.
• Robotics.
• Scanners.
• IoT Devices.
• Amplifiers.
• LED Screens/Display Modules.
• Other consumer electronics, industrial control, medical devices, and embedded systems (for applications requiring thin, high-density PCB layouts)

Automotive ECU/Control Unit Internals (Board-to-Board Stacking)

• Location: Engine ECU, Transmission TCU, Body Control Module (BCM)
• Form: Dual-row SMT male connector (main board) + female connector (daughter board) vertically snapped together
• Function: Transmits control signals, sensor data, and power
• Features: Temperature resistant -40℃~125℃, shock resistant, gold-plated contacts, long lifespan

• Certifications: Compliant with RoHS & REACH, UL standards.
• Packaging: Not detailed; typically supports Tray, Bag, Tube, Tape & Reel, etc. (common in this series).
• Ordering: Small and large volume orders accepted.
• Other Advantages: The company has a complete pitch series product line; materials meet environmental standards; stable workforce; and extensive production experience.

Precautions:

• This is an SMT type Box Header. During installation, strict control of the reflow soldering temperature curve and PCB flatness is required to avoid short circuits or placement misalignment caused by fine pitch.
• With a current of only around 1A, it's primarily suitable for signal transmission; for higher current requirements, we recommend considering the larger pitch series.
• Compared to the previously inquired 0.35mm/0.4mm ultra-fine pitch products, this 1.27mm series offers a larger pitch, higher mechanical strength, and a cost advantage, but is slightly larger in size.
• If your project requires a specific number of pins (e.g., 2x10, 2x20, etc.), different heights, taller versions, or shielding designs, we suggest providing your requirements for customization or recommendations from the manufacturer.
